Author: Juergen W. Heberle Publisher: ISBN: Category : Cone Languages : en Pages : 76
Book Description
Accurate experimental data are given on the shape and the location of detached shock waves on cones and spheres at Mach numbers from 1.17 to 1.81. The data are correlated to obtain equations that describe the shock waves. This knowledge of the shock waves should be useful in calculations of the pressure distribution and the pressure drag of the fore part of cones and spheres. The experimental data on shock waves are compared with theory.

Book Description
An experimental study was made of the changes in the stress-rupture life, ductility, hardness, and microstructure of S-816 and Inconel 550 specimens that had been exposed to varying amounts and conditions of thermal fatigue.

Book Description
Basic electrical networks are described that compensate for the thermal time lag of thermocouple and resistance thermometer elements. For a given set of operating conditions, networks requiring no amplifiers can provide a thirtyfold reduction in effective time lag. This improvement is obtained without attenuation of the voltage signal, but does result in a large reduction in the amount of electric power available because of an increase in the output impedance of the network. Networks used commercially available amplifiers can provide a thousandfold reduction in the effective time lag without attenuation of the alternating voltage signal or or the available electric power, but the improvement is often obtained at the expense of loss of the zero-frequency signal. The completeness of compensation is limited by the extent of off-design operation required.

Book Description
The compressive buckling stress of outstanding flanges reinforced by bulbs was computed by the strain-energy method for flanges having 10 shapes and a range of lengths. The results were checked for some cases by computations based on a differential-quation method. The edge of the flange opposite the bulb was considered clamped, and the loaded ends were considered simply supported.
